-exchange correction beyond the forward-angle limit in neutron decay
Hui-Yun Cao, Hai-Qing Zhou
In this work, we discuss the -exchange contributions in neutron decay with an elastic intermediate state, beyond the forward-angle limit (FAL). By decomposing the one-…

-exchange contribution in elastic scattering by perturbative QCD
Qian-Qian Guo, Hui-Yun Cao, Hai-Qing Zhou
In this study, we calculate the -exchange contribution to elastic scattering at large momentum transfer within perturbative QCD. We present analytical expressions for the…

-exchange contributions in neutron decay in the forward-angle limit
Hui-Yun Cao, Hai-Qing Zhou
In this work, the contributions from -exchange in neutron decay are estimated at the amplitude level. Using a general form for the electromagnetic (EM) form factors (FFs)…
